From the bottom of the yellow box on the scripts:
align is deprecated, paragraph elements can't contain block level elements, font element is deprecated, paragraph is closed incorrectly, instead another paragraph is opened.
<p style="text-align:center; font:xx-small 'arial', 'helvetica', sans-serif;">
I'll have a look around see what other scripts could use updating.
A couple of suggestions though, for scripts that require multiple files, have a zip file that users can download. It just makes it easier to retrieve all of the necessary componants.
